Route 13 and DuPont Highway Accident Lawyers
US 13, DuPont Highway, is Delaware’s spine. It runs from Wilmington and New Castle south through Dover, Camden, and Harrington, into Seaford and Laurel, and ends at Delmar on the Maryland line — a town the state boundary runs directly through.

One Road, Three Counties
Route 13 changes character repeatedly along its length. Through New Castle County it is a dense commercial corridor with constant turning movements. Through Kent County it becomes a high-speed divided highway past Dover Air Force Base and the Dover International Speedway. Through Sussex County it is the main artery connecting Seaford, Laurel, and Delmar. Each stretch produces a different crash pattern, from low-speed intersection collisions in the north to high-speed rear-end and crossover collisions further south.

Delmar and the Maryland Line
Route 13 ends its Delaware run at Delmar, a town that straddles the Delaware–Maryland border so completely that the state line runs through the middle of it. A collision on one block may be a Delaware case and a collision two blocks south a Maryland one. That distinction carries enormous weight, because Maryland applies pure contributory negligence and any share of fault on your part can bar recovery entirely. Record the exact cross street or address before the vehicles are moved.
Commercial and Agricultural Traffic
DuPont Highway carries freight the length of the state along with agricultural equipment through Kent and Sussex, poultry industry traffic in the south, and heavy seasonal volume feeding toward the beaches. Slow-moving equipment on a high-speed divided highway is a recurring hazard, and collisions involving commercial vehicles bring federal safety regulations and carrier-held evidence that is retained only for limited periods.
Intersections and Crossovers
Much of Route 13 south of Dover is divided highway with at-grade crossovers, where vehicles turn across high-speed traffic from a standing start. That design produces some of the most severe collision types on the road, including T-bone impacts at speed. Establishing sight lines, signal timing, and the sequence of movement usually requires the police reconstruction and any available camera footage, which makes prompt investigation important.

Frequently Asked Questions
Where does Route 13 cross into Maryland?
At Delmar, a town the Delaware–Maryland line runs directly through. One block can be Delaware and the next Maryland, and because Maryland applies contributory negligence, that distinction can decide whether you recover anything.
Is Route 13 more dangerous in one part of the state?
The pattern changes rather than the danger. Northern stretches produce dense intersection and turning collisions; the divided highway south of Dover produces high-speed rear-end and crossover crashes, which tend to be more severe.
I was hit at a crossover on DuPont Highway. What is involved?
Crossover collisions on divided highway typically involve a vehicle turning across high-speed traffic, producing severe T-bone impacts. Proving the sequence usually depends on the police reconstruction, sight line analysis, and any camera footage that still exists.
What about farm equipment and trucks on Route 13?
Slow-moving agricultural equipment on a high-speed highway is a recurring hazard through Kent and Sussex, and the corridor carries heavy freight. Commercial vehicle collisions bring federal safety regulations and carrier records that must be demanded early.
How long do I have to file after a Route 13 crash?
Delaware generally allows two years for personal injury claims. If the collision was on the Maryland side at Delmar, Maryland’s three-year period may apply instead. Do not rely on the longer one until which state governs is settled.
